Organization

Amedica Corporation was incorporated in the state of Delaware on December 10, 1996. Amedica Corporation is a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants and in a variety of industrial devices. At present, Amedica Corporation commercializes silicon nitride in the spine implant market and believes that its silicon nitride manufacturing expertise positions it favorably to introduce new and innovative devices in the medical and non- medical fields. Amedica Corporation also believes that it is the first and only company to commercialize silicon nitride medical implants. Amedica Corporation acquired US Spine, Inc. (“US Spine”), a Delaware spinal products corporation with operations in Florida, on September 20, 2010. Amedica Corporation and US Spine are collectively referred to as “Amedica” or “the Company in these condensed consolidated financial statements. The Company’s products are sold primarily in the United States.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the periods then ended. Actual results could differ from those estimates. The most significant estimates relate to inventory, stock-based compensation, long-lived and intangible assets and the liability for preferred stock and common stock warrants.

Actual results could differ from those estimates. Some of the more significant estimates relate to inventory, stock-based compensation, long-lived and intangible assets, goodwill, and derivative liabilities.

Reverse Stock Split

On November 10, 2017, the Company effected a 1 for 12 reverse stock split of the Company’s common stock. The par value and the authorized shares of the common and convertible preferred stock were not adjusted as a result of the reverse stock split. All common stock share and per-share amounts for all periods presented in these condensed consolidated financial statements have been adjusted retroactively to reflect the reverse stock split.

Reverse Stock Split

On January 25, 2016, the Company effected a 1 for 15 reverse stock split of the Company’s common stock. The par value and the authorized shares of the common and convertible preferred stock were not adjusted as a result of the reverse stock split. All common stock share and per-share amounts for all periods presented in these consolidated financial statements have been adjusted to reflect the reverse stock split.

Concentrations of Credit Risk and Significant Customers

Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, accounts receivable and restricted cash. The Company limits its exposure to credit loss by placing its cash and cash equivalents with high credit-quality financial institutions in bank deposits, money market funds, U.S. government securities and other investment grade debt securities that have strong credit ratings. The Company has established guidelines relative to diversification of its cash and marketable securities and their maturities that are intended to secure safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of trends in yields and interest rates and changes in the Company’s operations and financial position. Although the Company may deposit its cash and cash equivalents with multiple financial institutions, its deposits, at times, may exceed federally insured limits.

At December 31, 2016, one customer receivable balance was 16% of the Company’s total trade accounts receivable. At December 31, 2015, one customer receivable balance was 11% of the Company’s total trade accounts receivable. There was one customer that accounted for 10% or more of the Company’s revenue representing 17% of revenue for the year ended December 31, 2016. There was one customer that accounted for 10% or more of the Company’s revenue representing 12% of revenue for the year ended December 31, 2015.

Costs of Revenue

The expenses that are included in costs of revenue include all direct product costs if we obtained the product from third-party manufacturers and our in-house manufacturing costs for the products we manufacture. We obtain our non-silicon nitride products, including our metal and orthobiologic products, from third-party manufacturers, while we currently manufacture the majority of our silicon-nitride products in-house.

Specific provisions for excess or obsolete inventory and, beginning in 2013, the excise tax on the sale of medical devices in the United States, are also included in costs of revenue. In addition, we pay royalties attributable to the sale of specific products to some of our surgeon advisors that assisted us in the design, regulatory clearance or commercialization of a particular product, and these payments are recorded as costs of revenue.

Inventories

Inventories are stated at the lower of cost or market, with cost for manufactured inventory determined under the standard costs, which approximate actual costs, determined on the first-in first-out (“FIFO”) method. Manufactured inventory consists of raw material, direct labor and manufacturing overhead cost components. Inventories purchased from third-party manufacturers are stated at the lower of cost or market using the first-in, first-out method. The Company reviews the carrying value of inventory on a periodic basis for excess or obsolete items, and records any write-down as a cost of revenue, as necessary. It is reasonably possible that the Company may be required to make adjustments to the carrying value of inventory in future periods. Inventory write-downs for excess or obsolete inventory are recorded as a cost of revenue. The Company holds consigned inventory at distributor and other customer locations where revenue recognition criteria have not yet been achieved.

Accounts Receivable and Allowance for Doubtful Accounts

The majority of our accounts receivable is composed of amounts due from hospitals or surgical centers. Accounts receivable are carried at invoiced amount less an allowance for doubtful accounts. On a regular basis, we evaluate accounts receivable and estimate an allowance for doubtful accounts, as needed, based on various factors such as customers’ current credit conditions, length of time past due, and the general economy as a whole. Receivables are written off against the allowance when they are deemed uncollectible.

Derivative Liabilities

Derivative liabilities include the fair value of instruments such as common stock warrants, preferred stock warrants and convertible features of notes, that are initially recorded at fair value and are required to be re-measured to fair value at each reporting period under provisions of ASC 480, Distinguishing Liabilities from Equity, or ASC 815, Derivatives and Hedging. The change in fair value of the instruments is recognized as a component of other income (expense) in the Company’s consolidated statements of operations until the instruments settle, expire or are no longer classified as derivative liabilities. The Company estimates the fair value of these instruments using the Black-Scholes-Merton or Monte-Carlo valuation models depending on the complexity of the underlying instrument. The significant assumptions used in estimating the fair value include the exercise price, volatility of the stock underlying the instrument, risk-free interest rate, estimated fair value of the stock underlying the instrument and the estimated life of the instrument.

Advertising Costs

Advertising costs are expensed as incurred. The primary component of the Company’s advertising expenses is advertising in trade periodicals. Advertising costs were approximately $84,000 and $31,000 for the years ended December 31, 2016 and 2015, respectively.

Stock-Based Compensation

The Company measures stock-based compensation expense related to employee stock-based awards based on the estimated fair value of the awards as determined on the date of grant and is recognized as expense over the remaining requisite service period. The Company utilizes the Black-Scholes-Merton option pricing model to estimate the fair value of employee stock options. The Black-Scholes-Merton model requires the input of highly subjective and complex assumptions, including the estimated fair value of the Company’s common stock on the date of grant, the expected term of the stock option, and the expected volatility of the Company’s common stock over the period equal to the expected term of the grant. The Company estimates forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company accounts for stock options to purchase shares of stock that are issued to non-employees based on the estimated fair value of such instruments using the Black-Scholes-Merton option pricing model. The measurement of stock-based compensation expense for these instruments is variable and subject to periodic adjustments to the estimated fair value until the awards vest. Any resulting change in the estimated fair value is recognized in the Company’s consolidated statements of operations during the period in which the related services are rendered.

Because the Company was a privately-held company with no trading history prior to February 2014 and has limited stock history since February 2014, the Company utilizes the historical stock price volatility from a representative group of public companies to estimate expected stock price volatility and our historical stock price. The Company selected companies from the medical device industry, specifically those who are focused on the design, development and commercialization of products for the treatment of spine disorders, and who have similar characteristics to us, such as stage of life cycle and size. The Company intends to continue to utilize the historical volatility of the same or similar public companies to estimate expected volatility until a sufficient amount of historical information regarding the price of our publicly traded stock becomes available. The Company uses the simplified method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin No. 107, Share-based Payment, to calculate the expected term of stock option grants to employees as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The Company utilizes a dividend yield of zero because the Company has never paid cash dividends and has no current intention to pay cash dividends. The risk-free rate of return used for each grant is based on the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

The Company accounts for stock options to purchase shares of stock that are issued to non-employees based on the estimated fair value of such instruments using the Black-Scholes-Merton option pricing model. The measurement of stock-based compensation expense for these instruments is variable and subject to periodic adjustments to the estimated fair value until the awards vest. Any resulting change in the estimated fair value is recognized in the Company’s consolidated statements of operations during the period in which the related services are rendered.

New Accounting Pronouncement, Not Yet Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04 Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this guidance eliminate the requirement to calculate the implied fair value of goodwill used to measure goodwill impairment charge (Step 2). As a result, an impairment charge will equal the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendment should be applied on a prospective basis. The guidance is effective for goodwill impairment tests in fiscal years beginning after December 15, 2021. Early adoption is permitted for goodwill impairment tests performed after January 1, 2017. The impact of this guidance for the Company will depend on the outcomes of future goodwill impairment tests.

In August 2016, the FASB updated accounting guidance on the following eight specific cash flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. Under existing U.S. GAAP, there is no specific guidance on the eight cash flow classification issues aforementioned. These updates are effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, with early adoption permitted. The guidance in this standard is not expected to have a material impact on the financial statements of the Company.

In March 2016, the FASB updated the accounting guidance related to stock compensation. This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as the well as classification in the statement of cash flows. The standard is effective for the Company for its annual period beginning January 1, 2018. The guidance in this standard is not expected to have a material impact on the financial statements of the Company.

In February 2016, the FASB updated the accounting guidance related to leases as part of a joint project with the International Accounting Standards Board (“IASB”) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. Additionally, this update will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The standard is effective for the Company for its annual period beginning January 1, 2020, and interim periods therein, with early adoption permitted. The Company is currently evaluating the potential impact this new standard may have on its financial statements, but believes the most significant change will relate to building leases.

In May 2014, in addition to several amendments issued during 2016, the FASB updated the accounting guidance related to revenue from contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a company should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The standard defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is in the preliminary stages of evaluating the impact that the new standard will have on its financial statements.

The Company has reviewed all other recently issued, but not yet adopted, accounting standards, in order to determine their effects, if any, on its results of operations, financial position or cash flows. Based on that review, the Company believes that no other pronouncements will have a significant effect on its financial statements.

New Accounting Pronouncement, Not Yet Adopted

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330) Simplifying the Measurement of Inventory”. The amendments clarify that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Substantial and unusual losses that result from subsequent measurement of inventory should be disclosed in the consolidated financial statements. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those annual periods. The amendments are to be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. This guidance is not expected to have a material impact on the consolidated financial statements.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. Dilutive common stock equivalents are comprised of convertible preferred stock, warrants for the purchase of convertible preferred stock and common stock, convertible notes, and stock options and restricted stock units outstanding under the Company’s equity incentive plans. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position.

Potentially dilutive securities not included in the calculation of diluted net loss per share because to do so would be anti-dilutive are as follows (in common stock equivalent shares):
